I used samsung galaxy C5 phone last 2 months. There many improments are needed. First of all it cant handle even 3 apps sinultaniously. The phone is hanged every time when I used more than 1 app. Secondly, The battery is fall down very early. Phone is take more time to charge. Service centers people in gujarat india have not work properly. They don t respond to the customers. Always give time that come after 3 days, company can not give respond to our. So I suggest that improve your service centers and customer care services.
